To all 'whom t may concern:

Be it ltnown that 1, FRANK L. Fin-innen, a

citizen oi' the United States,` residing atr -i'or subsequentoperations.

T he invention involves the provision oiga rotary sup} 3ort ior holdingthe yarn while it is being rotated., and means for introducing moistureinto it at the same time in a fine spray and coming into contact withthe inner surfaces originally so that the moisture will be spreadthroughout the yarn by centrifugal force.

Reference is to be had to the accompanying drawings in which- Fig. l isa vertical central sectional view of a yarn moistening deviceconstructed in accordance with this invention;

Fig. 2 is a horizontal sectional view oi the same on the line 2-2 of Fig. 1, and

Fig. 3 is a view similar to Fig. 1, showing modifications.

ln the form shown in Figs. 1 and 2 i have provided a casing having abottom 11 for the machine. 0n. this bottom is a stepbear ing 12 carryingthe bottom or' a hollow shaft 13. This shaft is shown in these iiguresas being rotated by a belt 141 running on a pulley 15 at the top of theshaft, but in Fig. 8 a modification is indicated in which it is driven.at the bottom. At the top of this hollow shait 13 there is a bearing andstufl ing` box 16 for supporting it at that end.

T he casing 10 is provided inside with a ro tary casing 17 fixed on theshaft 13. ln this .rotary casing there are a plurality of radiallyarranged studs or the like 18 on which are mounted cops, bobbins, orspools 19 ofk the bearing and stufiing box 1G are mounted. This isprovided with ya'liollow head 21 at the top into which extends a pipeiitting 22 connected with a water supply pipe 23 and a steamsupply pipeThese are provided with valves 25 `and 26` respectively. rl`he'se valvesare so manipnlated as to cause the steam to `torce thewater into thehead 21 and down the pipe 13 and torce it out ott the "peri'iorationsinthe latter in thefo 'in et a"v fine spray. rihewhole circumference ofthe pipe 13 within the casing 17 is perforated so that the soraVT willbe uni'iorm all around Y y n .i w I W and rrom top to bottom. rlhecasing 11 ca be drained throughopenings 27 into thebot# tom of the outercasing 11 which is provided with drain pipes 28 fortakingcare ofy any`excess moisture."

In the form shown in Fig. 3, aside from the modification abovementioned, have shown a flexible supply pipe 32, otherwise v both formsof the invention work in the same way.

The operation is very simple. The yarn is placed in position and thecasing 17 with the pipe 13 started into operation. The steam and waterare regulated and intro duced so as to force the water out in a nesprayv mixed with steam into Contact with the inner ends of the balls orcops. The continued rotation acts to assist the action of capillaryattraction by centrifugal force to lead the moisture clear to the centerot each bobbin and clear to the outer end so that they will be moisteneduniformly. Furthermore7 if they should for any reason become too moistthe excess moisture will be thrown oiat the circumference against thecasing 17. The degree of moisture can be regulated by the valves 25 and26, but it is also regulated somewhat by the speed ot' rotation. In thisway an accurate and easily regulatable method of mostening the yarn isprovided.

.Although l have illustrated and described only two forms of theinvention I am aware of the fact that other modifications can be madetherein by yany person skilled in the kart without departing from thescope of the invention as expressed in the claims.

Therefore, 1 do not wish to be limited to allthe details of constructionherein shown 'and described, but what I do claim is 1. In a machine formoistening yarn, the

combination of a rotary casing having means for supporting a pluralityof packages of yarn arranged at intervals around its circumference, anda Central pipe about the center ot which said casing rotates, providedwith perfor-ations andhavng means for iritroducing moisture through saidpertorations 'into the interior of said casing against the surfaces ofthe yarn.

2. ln a machine for moistening yarn and the like, the combination otl acentral rotary hollow shaft or pipe, means for introducing steam andwater into said pipe, means for rotating the pipe on its own axis, andmeans mounted on the pipe at a distance therefrom for supporting` theyarn to he moistened.

ln n, machine for moistening yarn, the combination with a rotary pipeperforated for the escape of moisture, means for introducing water andsteam into said pipe, means for rotating said pipe, and a supportsurrounding said pipe and rotating therewith for balls of yarn.

e. In a machine for moistening yarn, the combination of a stationarycasing, a cover therefor, a hollow head at the top or said cover, pipesfor introducing steam and water into said hollow head, means forregulating the relative amounts of water and steam introduced, a stuiughoX and hearing under said head, a vertical hollow shaft Centered insaid stul'ing box and supported at t ie top by said bearing, means forrotating said shaft, a casing iXed on the bottom oil said shaft androtating therewith, said shaft having perforations therethroughthroughout the height of said easing, and a plurality of radial studsproj ecting inwardly from the exterior of said casing for supportingballs of yarn. u

5. In a machine for moistening yarn, the combination of a stationarycasing, means for introducing steam and water into said Casing, a hollowshaft extending through said easing, means for rotating said shaft,

an inner casing lixed on said shaft to rotate Y therewith, said shafthaving pert'orations `therethrough throughout the height of the innercasing, and a plurality of radial studs projecting inwardly from saidinner casing toward the shaft i'or supporting halls of yarn in aposition to be moistened by water and steam forced out 'through saidperforations.

In testimony whereof have hereunto afxed my signature.

FRANK L. FURBUSH.
